Vagina, Uterus, Oviduct

  • A: Stratified squamous epithelium is thick but it is also very light staining at the most apical surface. There is no keratin involved in the vaginal epithelium

    B: The muscular layer is smooth muscle irregularly arranged. This layer is also highly vascular. There is also no sign of distinct layers in the epithelial layer.
  • A: Stratified squamous epithelium

    B: Smooth muscle irregularly arranged. You can see the muscle fibers oriented in various different directions
  • A: Stratified squamous epithelium
  • A: Uterine gland

    B: Simple columnar epithelium lines the uterine tract

    C: Endometrium is made of two separate parts: The stratum functionalis which makes up the apical 2/3 and the stratum basalis which makes up the basal 1/3.
  • A: Simple columnar epithelium

    B: Uterine Glands
  • A: Simple columnar epithelium

    B: Uterine gland

    C: Stratum functionalis of the endometrium
  • A: Lamina propria is just beneath the epithelial layer and is loose connective tissue

    B: Ciliated simple columnar epithelium lines the lumen. The cilia are used to push the egg toward the uterus. The nuclei of this epithelium makes it easy to see where the epithelium is located and where the lamina propria begins.

    C: Muscularis externa makes up the exterior of the oviduct and also aids in propulsion of the egg.
  • A: Ciliated simple columnar epithelium is easily distinguished by the dark purple closely packed nuclei

    B: The lamina propria is filled with vasculature
  • A: Ciliated simple columnar. The cilia are clearly visible along the apical surface of the epithelial cells

    B: The loose connective tissue of the lamina propria
